MACHINE FOR PRINTING FABRICS.

i Specifcationof Letters Patent. i Patented Aug. 20, 1918' Application filed February 20, 1918. Serial No. 218,287.

-To all whom t may Gomera:

13e it known that I, GEORGE PRiFoLD, a citizen of the United States, and a resident of Linwood, county of Delaware, State of Pennsylvania, have invented certain Improvements in Machines for Printing Fab- Jirics, of which the following is a specificaion.

My invention relates' to certain improvements in machines for printing woven fabrics, particularly fabrics having a pile either cut, or uncut, where it is desired to cause the coloring matter to penetrate the fibers of the fabric so as toproduce a clear and permanent design.

This object I attain in the following manner, reference being had to the accompanying drawings, in which:

Figure 1 is a view, in diagram, illustrating my improved printing machine;

Fig. 2 is a plan view of a portion of the apron;

Fig. 3 is a longitudinal sectional view of a portion of the apron;

Fig. 4: is a diagram showing the woven fabric on the apron, and Figs. 5 and 6 are enlarged views showing one of the pins in the apron.

1 is a printing machine of the type such as that described in the patent granted to- Williani H. Waldron, No. 1,145,821, July 6,

1915. This machine consists of a frame 2v the fabric. This mechanism is also fully described in the patent hereinbefore alluded to, and forms no part of the present inveiition.

In the construction illustrated in the Waldron patent the fabric is traversed through the machine by being engaged by pms; on endless bands 8 at each side of the machine. The material has a base either of felt or woven burlap and the printing does not exl tend to the edge of the fabric.

This edge is cut after the printing has been completed, but, in printing textile goods, such as carp ets, woven rugs, or tapestries, it is essential that the printing shall extend from edge to edge of the fabric so as to retain the selvaged edge, thus preventing the fraying of the edges of the fabric and insuring a firm base forv the stitches where two or more lengths of fabric are secured by sewing. By my invention, the back of the body of the fabric is engaged preferably at numerous points so that the entire face can be printed, and at the same time the material is held positively while the blocks are making the impression so as to insure a proper register and a perfect impression.

This is accomplished by providing ian endless apron 3, which extends substantially the full length of the machine, and providing this apron with a series of pins 7, which project at an angle from the belt, as clearly shown in Figs. 3 and 6, the pins being of suflicient length to engage the base of the vfabric without penetrating the surface thereof and by arranging the pins at an angle, in the event of the pins penetrating through the fabric, the printing blocks will press the pins down in making the impression without injuring the/blocks or bending the pins. The pins project forwardly at an angle so as to more readily engage and pull the fabric, to be printed, through the machine.

In the present instance, the apron is driven by the endless driving bands 8 at each side of the machine and these driving bands have pins which engage the apron and the bands areintermittently moved by timed mechanism fully shown in the Waldion patent. I preferably make the apron endless, as shown in Fig. 1, and it passes around a guide roll 9 at one end of the machine and between squeeze rolls 10, then, as it leaves the machine it passes through feed rolls 11, around the guide rolls 12 and .13, over supporting rolls 14, and up over a guide roll 15 to the guide roll 9, but it will beunderstood that while I have described the means of carrying this apron, other means maybe employed without departing from the essential features of the invention.

The fabric ai. to be printed in the present is placed over the apron and between the squeeze rolls 10. r1`his forces the pins of the apron into the back of the fabric and as the apron moves intermittently through the machine it carries` the fabric with it, and as the pins hold the fabric firmly to the apron the proper registry of the printing is secured. The blocks are the full width of the fabric and print from one selvage edge to the other.

After the fabric passes through the machine it passes over a roller 1G, which is located directly above the apron and this roller draws the fabric from off of the pins and guides it to the drying rack, While the apron travels between the rear squeeze rolls and returns under the machine. The pins are arranged in a series of four points, in the present instance, and are spaced a given distance apart. The arrangement of the pins will depend considerably upon the thickness and weight of the carpet, or other fabric, to be printed.

Vhile l have shown the pins made in the manner illustrated in Fig. 4, and inclined forward, they may be made in any manner which will insure the positive attachment of the fabric to the apron.

By this construction, carpets, or rugs, can be printed in many different designs using anilin or equivalent colors` which will penetrate the fibers of the material and the imp essions will register properly so as to produce an effect equal to that produced by weaving previously colored strands of yarn.

l claim:

l. The combination in a machine for printing woven fabrics, of a frame; a bed; an endless apron arranged to travel over the bed; a series of printing blocks; reciprocating carriers mounted on the 'frame to which the blocks are secured; means for reciprocating the carriers so that they will make an impression on a fabric carried by the belt, the said apron having pins projecting at an angle to the surface thereof, the angle being such that when an impression is made by the block the pins Will yield and vvill not interfere with the printing ope ation.

2. The combination in a machine for printing Woven fabrics, of a frame; a series of vertically reciprocating carriers; printing blocks mounted on the carriers; an apron extending the full Width of the machine and having pins projecting from the surface thereof for engaging the fabric; squeeze rolls at the forward end of the machine through which the apron and the fabric pass to the machine, said squeeze rolls acting to press the fabric onto the pins of the apron, a pair of rolls at the discharge end of the machine between which the apron passes; and a stripping roll in advance of the last mentioned pair of rolls for removing the fabric from the carrier.

In Witness whereof l atlix my signature.

GERGE PRKFOLD.
